What is nacre?

Nacre, also known as mother of pearl, is an iridescent substance that forms the inner layer of certain mollusk shells, including oysters, abalones, and mussels. It is primarily composed of calcium carbonate and a protein called conchiolin.

Nacre is created by the mollusk as a protective barrier against irritants and parasites that may enter its shell. The mollusk secretes layers of nacre to cover the foreign object, resulting in the formation of a smooth, lustrous material with a characteristic shimmering appearance.

Due to its beauty and durability, nacre has been used in jewelry and decorative arts for centuries. It is often used to create pearls, as well as inlays for furniture, musical instruments, and other luxury items.

The color and iridescence of nacre can vary depending on the species of mollusk and environmental factors. It has a unique microstructure that diffracts light, giving it its signature rainbow-like effect.

Nacre is also valued for its strength and resilience, making it a popular material for use in architectural and industrial applications. Additionally, it is believed to have metaphysical properties that promote emotional balance and harmony.
